The post hoc fallacy is a widespread logical fallacy. Post hoc fallacy examples abound everywhere around us, and especially on the internet – where all fallacies are exposed sooner or later!
The full name of this fallacy is post hoc ergo propter hoc, which means “after this, therefore because of this” in Latin. In simple terms, a post hoc fallacy is one where when two events happen soon after each other, the occurrence of the second is attributed to the first.
Articles on fallacies are popular on the Home for Fiction blog. We’ve talked about the Appeal to Nature fallacy, the Bandwagon fallacy, and the Only Game in Town fallacy. Today I’ll talk to you about the Appeal to Hypocrisy fallacy, also known as “Tu Quoque”. The term is Latin and means “You, too”. I will use the terms interchangeably in this article, they mean exactly the same thing.
As with all fallacies, the Appeal to Hypocrisy is an attempt to ameliorate one’s argument with parameters that do not stand the test of argumentation and logic. Generally speaking, a person committing a fallacy might do it inadvertently; that is to say, without intent. Here’s an example:
Everyone at the office agrees, the boss is stupid.
This feels like a very natural thing to say. There doesn’t seem to be anything wrong with it, right? And yet, though the statement might still be true, it’s not argumentatively solid. The mere fact that every employee agrees, doesn’t prove that the boss is indeed stupid. This is an example of the Bandwagon fallacy.
Conversely, it is uncommon that a person would commit the Appeal to Hypocrisy fallacy unknowingly. The nature of this fallacy is such that the person deploying it in an argument is usually fully aware that his/her argument is weak, and the fallacy is committed precisely to create distraction.
Remember those commercials that talk about “only natural flavors” in a certain product? Caramels with natural flavors must be better than those with artificial ones, right? Well, not exactly. In actual fact, this designation only refers to the way a certain chemical is extracted. But it sure sounds better if you write “natural” on the package! Welcome to the Appeal to Nature Fallacy.
The Appeal to Nature Fallacy is… not really a fallacy, strictly speaking. It’s more of rhetorical trickery, rather, as the speaker tries to validate his or her argument by appealing to nature. One of the most notorious Appeal to Nature examples you might have seen is when someone homophobic attacks gay people claiming it’s “against nature”.
There are several different problems with this, so let’s see them one by one.
